RESUMEN
PURPOSE: Prevalence of myopia and vision impairment due to myopic macular degeneration and myopia-related optic neuropathies have markedly increased worldwide. We evaluated whether myopia is associated with other ocular disorders. DESIGN: Population-based studies conducted in Russia, China, and India. PARTICIPANTS: The Russian Ural Eye and Medical Study (UEMS) and the Beijing Eye Study (BES) included 5899 individuals and 4439 individuals (all aged 40+ years), respectively, and the Central India Eye and Medical Study (CIEMS) consisted of 4711 individuals aged 30+ years. The studies were conducted in rural and urban regions in Bashkortostan/Russia, Nagpur/India, and Beijing/China. METHODS: The participants underwent a series of ophthalmological and general medical examinations. MAIN OUTCOME MEASURES: Axial length as a surrogate for myopia and prevalence of diabetic retinopathy (DR), age-related macular degeneration (AMD), angle-closure glaucoma (ACG), and open-angle glaucoma (OAG). RESULTS: In the UEMS, DR prevalence (odds ratio [OR], 0.73), AMD prevalence (OR, 0.85), and ACG prevalence (OR, 0.72) decreased, and OAG prevalence (OR, 1.65) increased with longer axial length in multivariable analyses. In the CIEMS, lower AMD prevalence (OR, 0.81) and lower ACG prevalence (OR, 0.55), and higher OAG prevalence (OR, 1.45) were associated with longer axial length. Diabetic retinopathy prevalence (0.33%) was too low for statistical analysis in the CIEMS. In the BES, prevalence (OR, 0.64) and 10-year incidence of DR (OR, 0.48) and prevalence (OR, 0.83) and 5-year incidence of AMD (OR, 0.996) decreased, and prevalence (OR, 1.35) and 10-year incidence of OAG (OR, 1.40) increased with longer axial length. In all 3 studies, the association between higher OAG prevalence and longer axial length was nonlinear with a slight increase for the moderate myopia range and a steep increase in the highly myopic range. CONCLUSIONS: Myopia is associated with a lower prevalence of DR, AMD, and ACG and a lower incidence of DR and AMD, whereas high myopia more than moderate myopia is associated with a higher prevalence and incidence of OAG. Future studies may assess whether in myopia (in particular, in moderate myopia), the myopia-related advantages, that is, lower prevalence of DR, AMD, and ACG, may outweigh the increased risks for OAG and other myopia-related disorders.

RESUMEN
Our purpose was to evaluate the efficacy of lateral canthotomy, sub-tenon anesthesia injection, and the use of modified speculum for gaining adequate surgical exposure during surgery for retinopathy of prematurity (ROP). Fourteen eyes of 10 consecutive patients undergoing microincisional vitrectomy surgery (MIVS) for stage 4 and stage 5 ROP were included. There was a significant widening of the palpebral fissure height and length using this technique. No patient developed a lens injury during the surgery. All the canthotomy incisions completely healed at a four-week follow-up visit. This is a safe and effective technique for increasing surgical exposure in cases of ROP requiring vitrectomy.

Purpose: To report a case of a young female who presented with scotoma in the right eye for few days. Case Report: Krill's disease or acute retinal pigment epithelitis (ARPE) is a self-limiting retinal disease with no specific treatment. Typical clinical and imaging features helped us to diagnose her with ARPE. Intravenous methylprednisolone (IVMP), which gives a rapid anti-inflammatory response, was advised. An SD-OCT scan post-injection showed a reduction in hyperreflectivity and height of lesion at day 3 and near total resolution by day 5. Conclusion: This case suggests rapid resolution of ARPE with the use of IVMP.
RESUMEN
PURPOSE: To report the safety and efficacy of intravitreal bevacizumab (IVB) in a case of cystoid macular edema (CME) in a silicone oil-filled eye. METHODS: A man, aged 51 years, reported with poor visual improvement in the right eye (RE) after pars plana vitrectomy with oil injection performed 2 months back for a pseudophakic, macula-off rhegmatogenous retinal detachment. His best-corrected visual acuity in the RE was counting fingers 2 m. Fundus examination of the RE showed a silicone oil-filled eye with attached retina, and CME was confirmed on spectral-domain optical coherence tomography. He was advised to undergo IVB injection, which was given a few days later. RESULTS: One week after IVB, the central macular thickness had decreased to 437 µ m. Seven weeks later, the macular edema subsided completely with a final central macular thickness of 219 µ m. His vision improved by seven lines to 6/24 and was stable for another 2 months. He underwent removal of silicone oil after 3 months, wherein his visual acuity improved further by one line to 6/18. DISCUSSION: This case demonstrates the use IVB for CME in a silicone oil-filled eye. It was found that IVB was safe and effective in CME associated with a silicone oil-filled eye.
