The macular hole closure rate was similar with sulfurhexafluoride and perfluoropropane, irrespective of hole size, stage, or duration. However, sulfurhexafluoride exhibited a decreased incidence of cataract and ocular hypertension with shorter tamponade duration. Perfluoropropane may have a role as the preferred endotamponading agent in failed primary surgeries.

Polypoidal choroidal vasculopathy (PCV) is increasingly recognized as an important cause of exudative maculopathy in Asians as against Wet age-related macular degeneration in Caucasians. A panel of retinal experts methodically evaluated pertinent updated literature on PCV with thorough PubMed/MEDLINE search. Based on this, the panel agreed upon and proposed the current consensus recommendations in the diagnosis (clinical and imaging), management and follow-up schedule of PCV. Diagnosis of PCV should be based on the gold standard indocyanine green angiography which demonstrates early nodular hyperfluorescence signifying the polyp with additional features such as abnormal vascular network (AVN). Optical coherence tomography is an excellent adjuvant for diagnosing PCV, monitoring disease activity, and decision-making regarding the treatment. Current treatment modalities for PCV include photodynamic therapy, anti-vascular endothelial growth factor agents, and thermal laser. Choice of specific treatment modality and prognosis depends on multiple factors such as the location and size of PCV lesion, presence or absence of polyp with residual AVN, amount of submacular hemorrhage, presence or absence of leakage on fundus fluorescein angiography, visual acuity, and so on. Current recommendations would be invaluable for the treating physician in diagnosing PCV and in formulating the best possible individualized treatment strategy for optimal outcomes in PCV management.

Pilomatrix carcinoma is an uncommon malignant neoplasm originating from the hair follicle matrix. It occurs more frequently in head and neck region and rarely on the eyelid and eyebrow. It is often clinically misdiagnosed. The diagnosis is confirmed by excision biopsy and histopathological examination. A 68-year-old woman presented with a mass on her left eyebrow mimicking sebaceous cyst. An excisional biopsy with 4-mm margin was performed under frozen section. Histopathology demonstrated pilomatrix carcinoma with cystic degeneration. Periocular malignancies can have unusual origins with specific clinical features. Preoperative clinical examination is mandatory to rule out unusual features and thereby ensure appropriate management to prevent serious complications.

Context:Ocular complications due to diabetes mellitus (DM) were on the rise despite good literacy levels in South India.Aims:To assess the knowledge and attitude toward DM and diabetic retinopathy of the general population in a suburban town of South India.Settings and Design:Door-to-door population survey in suburban town of South India in May 2013.Materials and Methods:A 30-point questionnaire was prepared and the data were collected and analyzed to determine statistically the knowledge, attitude, and practice (KAP) scores of the general and diabetic population and also to determine significant demographic associations.Results:In this study, 6211 people (3528 [56.8%] women and 2683 [43.2%] men) with a mean age of 55.6 ± 11.7 years (range 21-98 years) were included. Good knowledge and positive attitude were observed in 3457 (55.6%) and 3280 (52.8%) people. Among 1538 (25.4%) people known to have DM, only 619 (40.7%) had good knowledge, 828 (53.8%) had a positive attitude, and 886 (57.6%) had good practice patterns. Although half of them followed general diabetic care, only 9.6% had undergone screening for retinopathy. Literacy showed a significant association with good KAP (P < 0.001 each) in general population and those with DM. Overall, women had significantly better knowledge (P < 0.001).Conclusions:Better literacy, especially among women, is contributory to better public awareness; however, the trend for poor practice patterns needs to be radically changed with aggressive public motivation emphasizing on the necessity of retinopathy screening and periodic follow-ups.

Chikungunya fever is a relatively rare from of vector-borne viral fever caused by chikungunya virus and spread by bites of the Aedes aegypti and Aedes albopictus mosquito. Epidemics of chikungunya fever have been reported in the past from different parts of the world. Although the virus had been passive for quite some time, recent reports of outbreaks of chikungunya fever in several parts of Southern India have confirmed the re-emergence of this virus. Symptoms of this infection include abrupt onset of fever, chills, and headache, rash, severe joint pain, conjunctival injection and photophobia. Ocular manifestations have been recently reported with this infection. We report a case of a 48-year-old female patient, who presented with defective vision two weeks after a serology proven chikungunya infection. There was bilateral neuroretinitis with peripapillary cotton wool spots. These findings should be kept in mind as an ocular manifestation of chikungunya virus infection.

Macular hole closure rate was similar in both the groups; however, smaller (3-mm) peel group demonstrated better functional improvement and nerve fiber layer preservation.

Aim:To provide the normative data of macular and retinal nerve fiber layer (RNFL) thickness in Indians using spectral domain OCT (Spectralis OCT, Heidelberg Engineering, Germany) and to evaluate the effects of age, gender, and refraction on these parameters.Design:Observational, cross-sectional study.Materials and Methods:The eyes of 105 healthy patients aged between 20-75 years, with no ocular disease and best corrected visual acuity of 20/20, were scanned using standard scanning protocols by a single examiner. Exclusion criteria included glaucoma, retinal diseases, diabetes, history of prior intraocular surgery or laser treatment. The mean macular and RNFL thickness were recorded, and the effects of age, gender, and refraction on these parameters were evaluated. This data was compared with published literature on Caucasians to assess the ethnic variations of these parameters.Results:The normal central foveal thickness in healthy Indian eyes measured using Spectralis OCT was 260.1 ± 18.19 μm. The nasal inner quadrant showed maximum retinal thickness (338.88 ± 18.17 μm). The mean RNFL thickness was 101.43 ± 8.63 μm with maximum thickness in the inferior quadrant. The central foveal thickness showed a gender-based difference (P = 0.005) but did not correlate significantly with age (P = 0.134), whereas the parafoveal, perifoveal thickness, macular volume, and RNFL thickness showed significant negative correlation with age.Conclusions:Our study provides the normative database for Indians on Spectralis OCT. It also suggests that age should be considered while interpreting the macular thickness and RNFL, whereas gender should also be given consideration in central foveal thickness.

Purpose: To suggest a low cost, non-contact smartphone-based screening system in retinopathy of prematurity (ROP), and to illustrate its potential clinical application as a potential future tool for teleophthalmology. Methods: Neonatal intensive care unit (NICU)-based bedside ROP screening done between January 2018 and May 2018. Documentation of ROP was done by using a smartphone and +40D, +28D, or +20D indirect non-contact condensing lenses. By using the coaxial light source of the phone, this system works as an indirect ophthalmoscope that creates a digital image of the fundus. With smartphone-based camera we extracted high-quality still images extracted from the video clip. Results: Total of 228 eyes of 114 infants screened for ROP between January 2018 and May 2018. Incidence of total ROP was 23.68%, out of which incidence of type 1 ROP was 8.77%. After initial screening with indirect ophthalmoscope, we uesd smartphone imaging to document ROP in 28 eyes out of 55 eyes having ROP. Image quality was good in 89.28% eyes. Field of view vary from 46°, 53°, and 90° with +20D, +28D, and +40D indirect condensing lenses, respectively, which gives excellent images for bedside ROP documentation. Conclusion: The described technique of smartphone fundus photography is a light weight, cost-effective, user friendly, high-quality wide-field fundus photographs for bedside documentation of ROP in NICUs using readily available instruments that are handy and portable with simple power sources. Smartphones has the potential to be operated with only one hand. It can also be used as a future telescreening device.
