Silent sinus syndrome (SSS) is an uncommon disease characterised by enophthalmos, caused by ipsilateral maxillary sinus atelectasis. The diagnosis is clinical with radiological confirmation. The treatment has two objectives: to regulate the aeration of the maxillary sinus through achieving normal nasal cavity drainage and to restore the orbital architecture.A case of SSS treated in our hospital in a single surgical intervention is reported. © 2011 Elsevier España, S.L.

Objetive: To screen for eye disease in diabetic patients by performing only an eye fundus examination with non-mydriatic retinography, or a more extensive ophthalmological examination including visual acuity (VA) and ocular tonometry. Material and methods: Design: A cross-sectional multicentre study with cohort comparison. Subjects: Diabetic patients who attended 6 Primary Health Care Centres (PCC). Interventions: complete ophthalmological examination of patients in 3 PCC: VA examination, intraocular pressure (IOP) measurement and eye fundus examination with non-mydriatic retinography (egphNMC). Partial examination of patients of the other 3 PCC: only an eye fundus examination with non-mydriatic retinography. Patients with a suspicion of eye disease were referred to the Ophthalmology Department. Results: A complete ophthalmological examination was carried out on 938 patients (71%) and a partial examination in 383 (29%). Diagnosis: a) suspicion of diabetic retinopathy (DR): 123 cases (9.3%), with no differences between the complete examination (9.1%) and partial examination (9.3%); b) suspicion of glaucoma: 89 cases (8.1% in complete examination and 3.4% in partial (suspicion due to papillary alteration in egphNMC)); c) VA changes: 169 cases (18%) in complete examination. Referral to ophthalmology service was made in 41% of patients with complete examination and 18% in patients with partial examination. Conclusions: Using only back of the eye examination with a non-mydriatic camera, a high percentage of diabetic patients were not diagnosed with an eye disease distinct to diabetic retinopathy (VA and IOP alterations), which are probably associated to a higher percentage of cataracts and glaucoma in this group. © 2012 Sociedad Española de Oftalmología.

Purpose. To assess the capacity of internal retinal layer thickness measurements made at the macula using new spectral-domain optical coherence tomography (OCT) software to distinguish between healthy subjects and those with suspected glaucoma. The diagnostic performance of such measurements also was compared with that of conventional peripapillary retinal nerve fiber layer (RNFL) thickness measurements.Methods. The study included 38 subjects with suspected glaucoma and 38 age-matched healthy subjects. In one randomly selected eye of each participant, thickness measurements at the level of the macula were made of the nerve fiber layer (mRNFL), the ganglion cell layer (GCL), and the ganglion cell complex (GCC; GCL + internal plexiform layer) through automated OCT segmentation. Peripapillary RNFL thickness (pRNFL) also was determined using the conventional scan.Results. As the only variable showing intergroup variation, mRNFL in the glaucoma suspects was significantly thinner in the quadrants inner inferior (P = 0.003), inner temporal (P = 0.010), and outer inferior (P = 0.017). The variable best able to discriminate between the two groups was inner inferior mRNFL thickness, as indicated by an area below the receiver operating characteristic (ROC) curve of 0.742.Conclusions. Macular RNFL thickness measurements showed an improved diagnostic capacity over the other variables examined to distinguish between healthy subjects and glaucoma suspects. © 2014 The Association for Research in Vision and Ophthalmology, Inc.

To estimate the frequency of unsuspected ocular surface squamous neoplasia (OSSN) in pterygium, the accuracy of clinical diagnosis, and associated demographic and clinical characteristics.We reviewed histopathological reports of patients with a clinical diagnosis of pterygium and/or OSSN who were surgically treated between March 2009 and December 2012 at the National Eye Institute in Lima, Peru. The accuracy of the clinical diagnosis of OSSN was assessed by sensitivity, specificity, and likelihood ratios. Models of negative log-log regression were performed to identify demographic and clinical characteristics associated with increased odds of diagnosing OSSN.3,021 histopathological reports were reviewed. The frequency of unsuspected OSSN in pterygium was 0.65%. Clinical diagnosis had a sensitivity of 85%, a specificity of 99%, a positive likelihood ratio of 111.89, and a negative likelihood ratio of 0.15. Associated characteristics were male gender (OR =1.15; 95% CI: 1.01 to 1.30), age group of 61-80 years (OR = 1.54, 95% CI: 1.28 to 1.85) 81 years (OR = 3.10; 95% CI: 2.09 to 4.58), presence of recurrent lesions (OR = 1.59; 95% CI: 1.03 to 2.46) and temporal location lesions (OR = 3.57; 95% CI: 2.63 to 4.85). These characteristics were associated with a greater likelihood of OSSN.A low frequency of unsuspected OSSN was found; however, it is recommended to routinely perform histopathology studies to avoid misdiagnosis of OSSN as pterygium.

To compare retinal sensitivity in diabetics with macular edema, with and without decreased visual acuity.An observational, prospective, cross-sectional comparative study in eyes with diabetic macular edema. The sample was divided into two groups: eyes with visual acuity 0.5 (group 1) and < 0.5 (group 2). Foveal sensitivity was compared between groups (Mann-Whitneys U), stratified according to the center point thickness. Correlations between visual acuity and retinal sensitivity and between visual acuity and macular volume were identified.81 eyes, 59 from group 1 and 22 from group 2. The mean of retinal sensitivity in group 2 (24.4 6.9 dB) was significantly lower than in group 1 (30.8 3.4; p < 0.001). The correlation between visual acuity and retinal sensitivity was 0.49 (r2 = 0.25), and it was 0.37 in eyes with center point thickness within one standard deviation above the mean and 0.40 in eyes within two standard deviations (p < 0.001). The correlation between visual acuity and macular volume was -0.108 (r2 = 0.026).Retinal sensitivity in eyes with clinically significant macular edema and decreased visual acuity before treatment was significantly lower than in eyes with normal visual acuity; the difference did not change as center point thickness increased.

Introduction Turkana is the largest district in Kenya, situated in the Northwest of the country. It features a semi-nomadic population of 850,000. Around 60% of population lives below the poverty threshold. The ratio of doctors is 1:75,000 inhabitants. Five ophthalmologists took part in the last deployment in November. Local staff had previously selected the patients from the rural areas, as well as in Lodwar, the capital of the district. Of the 371 patients who attended the clinic, 128 required surgery. Objetive To describe the pediatric population attended to in the last «Turkana Eye Project» Camp. Methods Description of the ophthalmic pathologies of the children seen in the clinic in this surgical camp, and the diagnostic and therapeutic options according to the limitations of the environment. Results Of the 371 patients, 54 were younger than 15 years old (14.5%). Four children had surgery (3.25% of the 128 patients). In 2 more cases surgery was the indicated but not performed. Therefore, of the total of 54 cases, 6 could be considered as surgical (11.1%), and 17 suffered ophthalmic problems other than refraction defects, or mild ocular surface pathologies: traumatic cataracts, neuropathies, impetigo, exophthalmos, retinal dystrophies, dermoid cysts, or nyctalopia. The etiology was traumatic in four of the 17 children (23.5%). Conclusion Surgical camps are increasing in the developing countries. They are usually focused on particular pathologies, such as cataracts or trachoma. Our case series shows the importance of pediatric teams and the need to be prepared to face complex pediatric pathologies. © 2011 Sociedad Española de Oftalmología. Published by Elsevier España, S.L.

The management of orbitary fractures is one of the most challenging in facial trauma; the variety of reconstruction materials for its treatment is broad and is constantly improving, but despite this there is no consensus for its use or literature that sustains it.To present the use and design of a preformed bone implant as an alternative for the reconstruction of orbital floor fractures in the pediatric age group.A 7-year old male who suffered a right hemifacial contusion trauma with clinical and tomographic diagnosis of right pure blowout type orbital floor fracture with inferior rectus muscle entrapment and right post-traumatic palpebral ptosis. Successful surgical reconstruction was performed 7 days later with a pre-constructed bone cement implant. Eight weeks after surgery the patient presented with mild residual palpebral ptosis, no ocular movement limitations and no diplopia.The use of a bone cement implant can be considered appropriate for the reconstruction of these fractures, as another alternative to be used by the ophthalmologist among the variety of all the other materials used for this purpose. We consider that our optimism based on the results obtained in this case obligates us to increase the number of patients treated in order to gather more evidence and do larger follow up.

Background: The neurorehabilitation of the patient with cerebral damage implies the reestablishment of the visual functions. Botu- linum toxin can be considerate as a less invasive alternative for treatment. Objective: to demonstrate the answer to the treatment using botulinum toxin of the visual motor alterations in patients with cerebral damage. Methods: Descriptive study of patients with visual alterations associated to cerebral damage. The visual treatment included three areas: sensorial, refracting and motor under quimiodenervation with botulinum toxin, of May 2009 to May 2010. Results: 48 patients were studied, age 22,4 years ± 23. The stra-bismus were: esotropia 52%, exotropia 39,5%, vertical 8%, nystagmus 4%. 50% of the patients had psychomotor delay. Some of the most important causes of cerebral damage were: Down syn-drome, epilepsy, tumor, hydrocephalus, neuroinfection, infantile cerebral paralysis, multiple sclerosis, metabolic syndrome, cranial trauma, congenital cardiopathy, ventricular hemorrhage, cerebro- vascular stroke. The dose of botulinum toxin was 8,1 UI ± 3. We registered good results in 56.5%, regular 23,9% and bad 19,5%. The global percentage of rehabilitation was 69% of correction with a r of Pearson of 0,5. Conclusion: The botulinum toxin is an effective option for the visual rehabilitation in patients with cerebral damage and prevents the progression of more cerebral changes secondary to strabismus.
