RESUMEN
PURPOSE: To find out clinical characteristics, therapeutic options, and visual outcome in symptomatic retinal artery macroaneurysm (RAMA) patients. METHOD: Newly diagnosed cases of symptomatic RAMA from January 2015 to December 2019 were included. Fifteen eyes of 15 patients with mean age 62.46 years ± 14.89 (SD) fulfilled the inclusion criteria. RESULT: Hypertension was present in 66.6% of the patients, and the commonest site was superotemporal (12 eyes, 80%). The most commonly employed treatment was Nd: Yag laser hyaloidotomy in 4 eyes (26.6%). Other treatments were intravitreal bevacizumab in 3 eyes (20%), focal laser with intravitreal bevacizumab in 3 eyes (20%), PPV with focal laser (13.3%) in 2, focal laser only in one (6.6%), PPV with focal and intravitreal bevacizumab in one (6.6%). The mean best-corrected visual acuity (BCVA) at baseline was 1.35 ± 0.84 LogMAR, which improved to 0.39 ± 0.53 LogMAR at the last follow-up. Presenting VA 0.77 (±0.40) improved to 0.20 (±0.17) p value (0.180) in intravitreal bevacizumab only group, 1.29 (±0.35) to 0.75 (±0.15) p value 0.66 in Nd: Yag laser group, 2.67 (±0.58) to 0.46 (±0.28) p value 0.019 in PPV group and did not improve in combined anti-VEGF and focal laser group due to dense hard exudates at the fovea in one and persistent cystoid macular edema in another case. CONCLUSION: With regard to its presentation, which can vary tremendously, there are no approved guidelines for its treatment. The present study reinforces the need for a treatment guideline development. Customization of treatment should be considered depending on the clinical presentation of each case.

BACKGROUND: Retinal diseases are very difficult to treat. So, early diagnoses and preventions are very important. But, few eye doctors can treat patients with retinal diseases in Nepal. Retina Eye Care of Nepal (RECON) project was designed to strengthen retina eye care services in Nepal. METHODS: RECON was implemented from May 2016 to February 2019 in Nepal. Four Master Eye Doctors (MED) received Training of Trainers (TOT) from Tokushima University, Japan. MEDs developed training materials for different cadres of ophthalmic human resources, enhanced retina eye care facilities, and conducted retina-screening camp in Nepal. RESULTS: Twenty ophthalmologists, 16 optometrists, 48 ophthalmic assistants and 17 ophthalmic nurses, 76 physicians and 28 health workers were trained in retina care. Eight outreach retina camps were conducted. CONCLUSIONS: The project was a novel approach to strengthen retina services in Nepal. The aim of the project was accomplished with the ultimate benefits to the needy retina patients who otherwise were going to miss the retina services.

BACKGROUND: Proper information on causes of childhood vision loss is essential in developing appropriate strategies and programs to address such causes. This study aimed at identifying the causes of vision loss in children attending the national referral eye hospital with the only pediatric ophthalmology service in Eritrea. METHODS: A retrospective data review was conducted for all the children (< 16 years of age) who attended Berhan Aiyni National Referral Eye Hospital in five years period from January 2011 to December 2015. Causes of vision loss for children with vision impairment (recorded visual acuity less than 6/18 for distance in the better eye) was classified by the anatomical site affected and by underlying etiology based on the timing of the insult and causal factor. RESULTS: The medical record cards of 22,509 children were reviewed, of whom 249 (1.1%) were visually impaired. The mean age of the participants was 7.82 ± 5.43 years (range: one month to 16 years) and male to female ratio was 1:0.65. The leading causes of vision loss were cataract (19.7%), corneal scars (15.7%), refractive error and amblyopia (12.1%), optic atrophy (6.4%), phthisis bulbi (6.4%), aphakia (5.6%) and glaucoma (5.2%). Childhood factors including trauma were the leading causes identified (34.5%) whereas other causes included hereditary factors (4%), intrauterine factors (2.0%) and perinatal factors (4.4%). In 55.0% of the children, the underlying etiology could not be attributed. Over two-thirds (69.9%) of vision loss was potentially avoidable in nature. CONCLUSION: This study explored the causes of vision loss in Eritrean children using hospital based data. Cataract corneal opacities, refractive error and amblyopia, globe damage due to trauma, infection and nutritional deficiency, retinal disorders, and other congenital abnormalities were the leading causes of childhood vision impairment in children attending the tertiary eye hospital in Eritrea. As majority of the causes of vision loss was due to avoidable causes, we recommended primary level public health strategies to prevent ocular injuries, vitamin A deficiency, perinatal infections and retinopathy of prematurity as well as specialist pediatric eye care facilities for cataract, refractive errors, glaucoma and rehabilitative services to address childhood vision loss in Eritrea.

Purpose: To quantify metamorphopsia in patients with resolved idiopathic Central Serous Chorioretinopathy (CSCR) using M-CHARTS and compare the results with the traditional Amsler grid and optical coherence tomography (OCT). Patients and Methods: For the purpose of this study, all consecutive cases of patients with resolved CSCR were evaluated for metamorphopsia (using the standard Amsler grid and M-CHARTS) and spectral domain OCT. The OCT images were analyzed for the following five parameters: central macular thickness, pigment epithelial detachment, retinal pigment epithelial bumps, discontinuation in the inner segment/outer segment junction or the external limiting membrane, fibrinous exudates in the subretinal space, and hyperreflective dots in the intraretinal and/or subretinal layer. Binary logistic regression was used to find the association between metamorphopsia and foveal morphology. Cohen's Kappa was used to determine the agreement between the M-CHARTS and Amsler grid for diagnosing metamorphopsia. The sensitivity, specificity, and accuracy in the diagnosis of metamorphopsia were calculated against the Amsler grid. Results: Of 41 eyes, Amsler Grid detected metamorphopsia in 39.02%, and M-CHARTS detected metamorphopsia in 53.66%. The agreement rate of detection between the two tests was moderate (Kappa=0.52). M-CHARTS had a sensitivity of 87.50%, a specificity of 68.00%, a positive predictive value of 63.64%; and a negative predictive value of 89.47% for the diagnosis of metamorphopsia compared to the Amsler grid. The presence of PED in OCT was significantly associated with metamorphopsia. Conclusion: M-CHARTS can be a useful ancillary test to detect and quantify metamorphopsia even after fluid resolution in CSCR. Structural changes in macular morphology as observed with OCT can predict the likelihood of metamorphopsia.
RESUMEN
PURPOSE: To compare improvements in visual acuity (VA) and stereoacuity between active vision therapy (AVT) and conventional patching therapy in children with amblyopia. METHODS: This study included 65 children aged 5 to 16 years (mean age±SD, 11.00±3.29 years) with unilateral amblyopia. Among them, 31 children underwent active vision therapy (AVT group), and 34 children underwent conventional patching therapy (patching group). AVT group underwent three sequential phases of AVT: Monocular phase (pursuit, saccades, fixation, visuomotor, eye-hand coordination, and central peripheral activities), biocular phase (diplopia awareness, antisuppression, monocular fixation in a binocular field, accommodative activities, bilateral integration, and fine motor activities) and binocular phase (fusion and stereopsis). Patching group patched their fellow eyes as per guidelines by Pediatric Eye Disease Investigator Group. Best-corrected monocular VA and stereoacuity were measured at baseline and after three months of therapy in both groups. RESULTS: There were significant improvements in the mean acuities in amblyopic eye (AE) in both AVT (0.32±0.11 logMAR, p <0.001) and patching groups (0.27±0.19 logMAR, p Ë 0.001). However, there was no significant difference in mean acuity gains in AE between AVT and patching groups (p = 0.059). Mean gains in stereoacuities (log seconds of arc) were statistically significant in both AVT (0.81±0.34, p < 0.001) and patching groups (0.32±0.34, p < 0.001). The stereoacuity gain in the AVT group was significantly higher compared to patching group (p < 0.001). CONCLUSION: Active vision therapy had a better impact than conventional patching therapy in terms of improvement of stereoacuity but not in terms of VA when used for treating children with amblyopia.

Introduction: Diabetic retinopathy is a specific microvascular ocular complication associated with diabetes. However, retinopathy has also been reported in people with prediabetes. The study aimed to find out the prevalence of diabetic retinopathy among patients with prediabetes attending the outpatient Department of Ophthalmology in a tertiary eye care centre. Methods: A descriptive cross-sectional study was conducted among patients with prediabetes attending the outpatient Department of Ophthalmology in a tertiary eye care centre from 1 January 2022 and 30 April 2022. Ethical approval was obtained from the Ethical Review Board (Registration number: 594/2021 P). All patients had their eyes dilated and examined under the slit-lamp with a 90 D convex lens or indirect ophthalmoscopes with a 20 D lens to find retinopathy. All patients aged 40 to 79 years with intermediate hyperglycemia were included in the study. Convenience sampling was used. Point estimate and 95% Confidence Interval were calculated. Results: Among 141 patients with prediabetes, diabetic retinopathy was found in 8 (5.67%) (1.85-9.49, 95% Confidence Interval). Among which all patients 8 (5.67%) had mild non-proliferative diabetic retinopathy. Among patients with retinopathy, all 8 (5.67%) were obese, 3 (37.50%) were hypertensive, 5 (62.50%) patients had intermediate hyperglycemia for more than 6 months, and 2 (25%) had a family history of diabetes mellitus. Conclusions: The prevalence of diabetic retinopathy in prediabetes patient was found to be higher than the other studies conducted in similar settings. Keywords: diabetic retinopathy; prediabetes; prevalence.

BACKGROUND: Land use and land cover changes have a significant impact on the dynamics of soil organic matter (SOM) and its fractions, as well as on overall soil health. This study conducted in Bharatpur Catchment, Chitwan District, Nepal, aimed to assess and quantify variations in total soil organic matter (TSOMC), labile organic matter fraction (CL), stable organic matter fraction (CS), stability ratio (SR), and carbon management index (CMI) across seven land use types: pastureland, forestland, fruit orchards, small-scale conventional agricultural land, large-scale conventional agricultural land, large-scale alternative fallow and conventional agricultural land, and organic farming agricultural land. The study also explored the potential use of the Carbon Management Index (CMI) and stability ratio (SR) as indicators of soil degradation or improvement in response to land use changes. RESULTS: The findings revealed significant differences in mean values of TSOMC, CL, and CS among the different land use types. Forestland and organic farming exhibited significantly higher TSOMC (3.24%, 3.12%) compared to fruit orchard lands (2.62%), small scale conventional farming (2.22%), alternative fallow and conventional farming (2.06%), large scale conventional farming (1.84%) and pastureland (1.20%). Organic farming and Forestland also had significantly higher CL (1.85%, 1.84%) and CS (1.27%, 1.39%) compared to all other land use types. Forest and organic farming lands showed higher CMI values, while pastures and forests exhibited higher SR values compared to the rest of the land use types. CONCLUSIONS: This study highlights the influence of various land use types on soil organic matter pools and demonstrates the potential of CMI and SR as indicators for assessing soil degradation or improvement in response to land use and land cover changes.
RESUMEN
INTRODUCTION: As the number of people with diabetes mellitus is increasing because of urbanization and change in dietary habits and sedentary lifestyle, the number of diabetic retinopathy is also expected to increase in future. [1] [sa2] We aimed to find out the prevalence of diabetic retinopathy and associated risk factors among diabetic patients in the tertiary eye hospital. MATERIALS AND METHODS: This is the observational cross-sectional study enrolling 420 diabetic patients visiting the multispecialty tertiary eye hospital between March 2020 and February 2021. Anthropometry measurement, laboratory risk profiles and blood pressure were recorded Results: The prevalence of any diabetic retinopathy, proliferative diabetic retinopathy, and diabetic macular edema were 30.96 %, 6.19 %, and 5.95 % respectively. The duration of DM (p=0.001), hypertension (p=0.04), high SBP (p=0.023), abdominal obesity (p=0.015), high LDL(p=0.011) cholesterol, low HDL cholesterol(p=0.012), and creatinine (p=0.001) were associated with DR in our study. CONCLUSION: A holistic approach should target to control the modifiable risk factors like blood sugar, blood pressure, lipid profile, kidney function, and obesity to prevent DR. Anthropometric assessment of waist to height and waist circumference should be included in the holistic health promotion strategy in Nepal as BMI may not be risk factors for DR in Nepalese people.

INTRODUCTION: Major cause of irreversible blindness is glaucoma which is increasing as a significant global health problem. Knowledge of glaucoma burden and its clinical characteristics in this region is essential. MATERIALS AND METHODS: This was a cross-sectional hospital -based study conducted at Glaucoma unit in CHEERS Hospital, Bhaktapur from August 2015 to July 2019. Patients' demographic profile, along with comprehensive eye examination findings were reviewed from the records. Data analysis was done with IBM SPSS version 24 and was presented in mean (±SD), frequency and proportions and a chi- square test was applied. P value < 0.05 was considered statistically significant. RESULTS: Total of 310 glaucoma cases were included in this study. The mean age presentation was 61.89±14.4 years, and the majority of patients (52.9%) were in the age group 60-79 years. Most patients had primary open angle glaucoma (171, 55.2%) followed by primary angle closure glaucoma (92, 29.7%). CONCLUSION: Primary open angle glaucoma is the most common form of glaucoma. The proportion of glaucoma increased with increasing age (> 40 years). Provision of screening programs targeting persons with risk factors and opportunistic eye examinations would be beneficial in detection of glaucoma.

INTRODUCTION: Despite best possible preventive measures, acute postoperative endophthalmitis (POE) is still the most devastating, sight-threatening complication after intraocular surgery and the most feared complication by treating surgeons. MATERIALS AND METHODS: It is a retrospective study of 22 eyes diagnosed as acute POE following cataract surgery in the last 5 years (2015-2019), aimed to evaluate the treatment strategies used in its management. Main outcome measures evaluated were rates of repeat intravitreal injection, adjunctive therapeutic regimens, pars plana vitrectomy (PPV) and visual outcome. RESULTS: Twenty one eyes (95.45%) received repeated intravitreal injection. Adjuvant intravitreal steroid was used in 12 eyes (54.54%), oral steroid in 16 eyes (72.72%) and oral antibiotic in 8 eyes (36.36%). PPV was done in 8 eyes (34.78%) and all 8 eyes that underwent PPV had a vision of Hand Movement (HM) close to face. 7 eyes (87.5%) had early PPV within 1 week of diagnosis. The median best corrected visual acuity (BCVA) improved from 1.00 logMar to 0.8 logMar following treatment at 3 months follow up (p= 0.117). CONCLUSION: Repeat intravitreal injections were commonly employed. Early PPV was performed more commonly regardless of the visual acuity at the time of diagnosis of acute POE.

PURPOSE: To report a case of high-altitude retinopathy with vitreous hemorrhage. METHODS: An apparently healthy 29-year-old boy presented with a history of floater and slight diminution of vision in the left eye after climbing the mountain 4760 meters high. RESULTS: The visual acuity at presentation was 20/20 in the right eye and 20/30 in the left eye. Anterior segment findings of both eyes were unremarkable. Fundus evaluation revealed bilaterally dilated major retinal veins. The right eye revealed clear, quiet vitreous, healthy macula, and pink and smooth optic disc. There was fresh vitreous hemorrhage confined just one disc diameter away at the superior and inferior part of the optic nerve in the left eye. The macula and optic nerve head of this eye grossly looked normal. Complete blood count, haemoglobin, ESR, CRP, sugar, renal function test, lipid panel, and serology for HIV, HCV, VDRL, and HBsAg were normal. The Mantoux test and chest X-ray also revealed normal findings. Physician consultation did not reveal other abnormalities. On the 3rd week of follow-up, his vision was 20/20 in both eyes. Fundus examination revealed clear vitreous in both eyes though some venous dilation and tortuosities were still evident in the left eye. A macular OCT scan showed almost normal-appearing fundus. CONCLUSIONS: Vitreous hemorrhage following climbing high altitude can be one of the manifestations of high-altitude retinopathy.
RESUMEN
INTRODUCTION: Intravitreal Bevacizumab injection has now become a routine procedure for retina specialists throughout the world. Easy availability of this monoclonal antibody molecule even in Nepal has brought a revolution in the management of various retinal diseases. This study aims to find out the prevalence of the use of intravitreal Bevacizumab for retinal diseases at the tertiary eye hospital. METHODS: This descriptive cross-sectional study was carried out in the retina department at a tertiary care hospital from January 2017 to December 2019 after obtaining ethical clearance from Nepal Health Research Council (Ref: 125/2020P). The sample size was calculated and the study enrolled all patients who received intravitreal Bevacizumab for retinal diseases using convenience sampling technique. Data were analyzed using Statistical Package for Social Science Version 21. Point estimate at 95% Confidence Interval was calculated, along with frequency and percentage for binary data. RESULTS: Out of 959 total surgical retinal interventions done 296 (30.86%) at 95% Confidence Interval (27.93-33.78) patients received intravitreal Bevacizumab. Out of total intravitreal Bevacizumab injections, 143 (36.7%) injections were given to retinal vein occlusions patients, 127 (32.6%) injections were given to diabetic retinopathy patients and 66 (17%) injections was given to age-related macular degeneration patients. Males 176 (59.5%) outnumbered the females 120 (40.5%) in receiving intravitreal Bevacizumab. Mean baseline Logarithm of the Minimal Angle of Resolution visual acuity, 1.1, improved to, 0.75, after 3 months of intravitreal Bevacizumab. CONCLUSIONS: Intravitreal Bevacizumab was one of the commonest retinal interventions used. Retinal vein occlusion, diabetic retinopathy, and age-related macular degeneration were the commonest retinal diseases needing intravitreal Bevacizumab.

Artificial fruit ripening agents have become increasingly popular in recent years. During the off-seasons, various ripening agents are used for the ripening of banana fruits. The effects of various ripening agents of banana fruits (variety: Malbhog) were studied. Seven treatments consisting of distilled water, Gibberellic acid (GA3) @ 100 ppm, GA3 @ 200 ppm, GA3 @ 300 ppm, kinetin @ 3 ppm, kinetin @ 5 ppm, and kinetin @ 7 ppm were laid out in a Completely Randomized Design with three replications. The maximum loss in weight (9.195%), Total Soluble Solids (20.33ËB), the highest color score (6), pH (4.767), Total Soluble Solids/Titratable Acidity TA (34.23), and Pulp peel ratio (2.84) were observed in banana sprayed with distilled water whereas the minimum value for TSS (12.67ËB), pulp peel ratio (1.813), peel color rating (2.67), TSS/TA (15.32) were observed in GA3 @ 300 ppm treated fruits. The maximum (32.67 days) and the minimum (18.33 days) shelf-life was observed in GA3 @ 300 ppm and distilled water respectively. This research will help in the regulation of ripening as per the needs of consumers and the distance of the market. In horticulture, it will help to extend storage life and reduce quality and economic loss.
RESUMEN
BACKGROUND: Recently, the number of retinal patients is increasing in Nepal. The retinal problems are the second common cause of blindness in Nepal. Retinal diseases are challenging to manage due to the lack of simple and cost-effective screening methods, limited human resources, poverty, and lack of awareness in Nepal. Hospital for Children, Eye, ENT & Rehabilitation Services (CHEERS), Nepal conducted retina screening camps and education in communities through Retina Eye Care of Nepal project (RECON) in the years 2017 and 2018. MATERIALS AND METHODS: We screened retinal patients with an indirect ophthalmoscope coupled with plus 20 Dioptre lens and portable fundus camera. We referred the patients needing interventions to the base hospital (CHEERS) using a screening algorithm, where they received retinal laser and surgery. Besides, we also provided on-site educational programs for retinal disease awareness to the community. RESULTS: Retinal problems found from two static outreach clinics (SORC) and a day screening and treatment service (DSTS) were 18.3%, 20%, and 20%, respectively, while from a remote rural health camp (RRHC) was 2.61%. Likewise, patients referred to CHEERS for retinal laser or other retinal interventions were 15%, 16.6%, 16%, and 1.96% from 2 SORCs, 1 DSTS, and 1 RRHC, respectively. CONCLUSION: Retina camp is a cost-effective approach to early detection and referral for retinal-related vision impairment patients. It is also one opportunity to educate the community. The purpose of the project was to provide retina care to the community who otherwise could not afford it. We recommend a similar screening model on a large scale in a low-resource setting for the maximum benefits to the rural community.
RESUMEN
INTRODUCTION: Ticks are ectoparasites which can lead to various blood borne diseases. Tick bite may resemble pigmented nevi, mole or nodule resulting a diagnostic dilemma. Tick bite in eye lid is rare and this case report describes tick bite in lower eye lid mimicking a traumatized pigmented nodule where the tick was identified only on magnification and was successfully removed mechanically. CASE: A 61-year-old man presented to the eye out patient department with a sudden and painful black pigmented lesion on the right lower lid for four days. The tick was manually removed with forceps. CONCLUSION: This case report explains the need for a high index of suspicion as tick bite in sudden or recent onset pigmented lesions especially in endemic areas.

BACKGROUND: To determine the influence of spectral domain optical coherence tomography (OCT) changes on visual outcome and persistence of subretinal fluid (SRF) in patients with idiopathic central serous chorioretinopathy (CSCR). MATERIALS AND METHODS: In a retrospective study done in 48 eyes of 45 patients diagnosed as CSCR, all eyes were subjected to fundus photography, spectral domain OCT, and fluorescein angiography (FA) in selected cases. RESULTS: Retinal pigment epithelium detachment was present in 22.91% of the cases at presentation. The logMar best corrected visual acuity improved from 0.46±0.29 at presentation to 0.18±0.22 at 3 months (P-value<0.01). The mean foveal thickness was 486.81±146.06 µm at presentation and 259±94.5 µm at 3 months (P-value<0.01) (paired T-test). OCT factors that were associated with poor visual outcome (BCVA>0.3 logMar) were disruption in the inner segment (IS)/outer segment (OS) junction or external limiting membrane (ELM) line and hyper-reflective dots in the intra/subretinal layer (P-value<0.05) (Fischer's Exact test). Out of the total 48 eyes, 26 had persistent SRF at 3 months. The presence of discontinuation in IS/OS junction and hyper-reflective dots in the intra/subretinal layer were the only two OCT factors that were associated with the persistence of SRF (P-value<0.01) (Pearson's Chi-square test). CONCLUSION: Visual outcome and persistence of subretinal fluid at 3 months can be predicted on the basis of early morphologic changes in OCT. This will aid in counseling patients regarding its course and may guide us in its management.
RESUMEN
Neopicrorhiza scrophulariiflora (Pennell) D. Y. Hong of Scrophulariaceae family (hereinafter referred to as Neopicrorhiza) has medicinally important rhizomes with high levels of trade. What factors drive demand for Neopicrorhiza in Central Himalaya is unknown. In this context, a nationwide comprehensive survey was conducted from September 2016 to March 2017 to assess demand, end-uses, and conservation of dry Neopicrorhiza rhizomes in Nepal. A total of 2313 herbal products were surveyed for Neopicrorhiza as an ingredient in 38 retailer shops. Processing industries of Neopicrorhiza in Nepal were interviewed using structured questionnaire. There were 23 herbal industries manufacturing 45 types of ayurvedic medicines as end-products containing Neopicrorhiza. The volume and value of annual demand for dry rhizomes of Neopicrorhiza in Nepal were found as 6076 kg and NRs 8573236 (USD 83235.30), respectively, in 2015/016 with average 264.17 kg/industry and NRs 1410.87 (USD 13.69) per kg. The major uses of ayurvedic medicines containing Neopicrorhiza were to treat a number of disease categories: cardiovascular system/liver (17), cardiovascular system/blood (6), nervous system (6), dermatological system (4), musculoskeletal system (3), digestive system (2), respiratory system (2), genitourinal system (4), and others (1). Despite changing legal regulation, trade and consumption of Neopicrorhiza exist in Nepal. It can be concluded that domestic consumption is not the major cause of resource depletion of Neopicrorhiza in Nepal.
RESUMEN
Spasm or contracture of gastrocnemius causes an equinus deformity of the ankle in both cerebral palsy and hemiplegia. Its release is therefore required in the treatment of those patients who do not respond to conservative measures. The Vulpius procedure is a simple and effective method for the release of gastrocnemius and is particularly indicated when long periods of immobilisation of the foot and ankle are not desirable. We have used this procedure with good results to correct an equinus deformity in 230 adults with a cerebrovascular accident and various associated medical conditions. It is not only effective in cerebral palsy, but should be considered at an early stage in all adult patients with deformity of the ankle and foot in whom spasm of gastrocnemius is the major cause.

AIM: To find out the outcome of laser photocoagulation in clinically significant macular edema (CSME) by optical coherence tomography (OCT) METHODS: It was a prospective, non-controlled, case series study enrolling 81 eyes of 64 patients with CSME between August 2008 and January 2010. All patients received modified grid photocoagulation with frequency doubled Nd: YAG laser. Each patient was evaluated in terms of best-corrected visual acuity (BCVA) and regression or progression of maculopathy after laser therapy at 1, 3 and 6 months. Spearman's correlation test was used to show the correlation between BCVA and total macular volume (TMV). Analysis of variance (ANOVA) was used to compare among groups and independent t-test was used to compare in each group. RESULTS: There is high correlation between BCVA and TMV (P≤0.001). BCVA improved in 50.6 %, remained static in 39.5% and deteriorated in 9.9% patients after 6 month of treatment. The Baseline TMV (mean and SD) were 9.26±1.83, 10.4±2.38), 11.5±3.05), 8.89±0.75 and 9.47±1.98mm(3) for different OCT patterns, ST (sponge like thickening), CMO (cystoid macular edema), SFD (subfoveal detachment), VMIA (Vitreo macular interface abnormality) and average TMV respectively (P=0.04). After 6 months of laser treatment, the mean TMV decreased from 9.47±1.98mm(3) to 8.77±1.31mm(3) (P=0.01). In ST there was significant decrease in TMV, P=0.01, Further within these groups at 6 months, they were significantly different, P=0.01. CONCLUSION: OCT showed the different morphological variant of CSME while the response of treatment is different. TMV decreased the most and hence showed the improvement in vision after 6 months of laser treatment. In the era of Anti vascular endothelial growth factors (VEGFs), efficacy of laser seems to be in shadow but it is still first line of treatment in developing nation like Nepal where antiVEGFs may not be easily available and affordable.
