“…In our study, presenting mean log MAR BCVA was 0.47 and final mean log MAR BCVA was 0.18 (p <0.01) with a strong positive correlation between initial and final BCVA. Promising visual results were reported in various international studies with baseline log MAR BCVA ranging from 0.21 -0.40 that had improved to final Log MAR BCVA in the range of 0.00-0.14 8-12,13,17. Wong et al found that acute CSCR that resolved spontaneously or following treatment had a good long term prognosis for visual functions 18.…”

Objective:To determine the visual outcome in patients with acute Central serous chorioretinopathy (CSCR) and to analyze the association of clinical, angiographic and tomographic factors with final visual outcome in Pakistani population.Methods:This study was conducted at AFIO Rawalpindi and PNS Shifa Naval hospital Karachi from November 2011 to August 2016. Fifty five eyes of 53 patients with acute CSCR were included. All patients underwent a detailed ophthalmic examination including SD OCT imaging at baseline, One month and three month and FFA was performed at baseline. Primary outcome measures were measurement of initial and final BCVA and CFT. SPSS 13.0 was used for the analysis of data.Results:Mean age of study population was 36.66 ± 6.24 years. On OCT mean CFT at baseline was 467.49 ± 144.80 µm in affected eye, whereas mean CFT measurements at final follow up was 244.67 ± 32.99 µm (p <0.01). Presenting mean log MAR BCVA was 0.47 ± 0.25 and final mean log MAR BCVA was 0.18 ± 0.14 (p <0.01). Baseline BCVA showed statistically significant association with final BCVA (p=0.03).Conclusion:Presenting VA of 6/12 or better is associated with favorable visual outcome in patients with acute CSCR.

“…There are studies describing visual acuity and fixation stability improvement by visual rehabilitation, using microperimeter MAIA, in patients with successful closure of macular hole [7], AMD [8] and another studies carried out on the device MP-1 in patients with myopic macular degeneration and other macular diseases [9][10][11]. Additionally, it has been proven that microperimetry is a useful tool for www.journals.viamedica.pl/ophthalmology_journal the follow-up of patients with diabetic retinopathy [12][13][14][15], central serous chorioretinopathy [16,17], uveitic macular edema [18], macular dystrophies such as Stargardt disease [19], and AMD, in the latter evidencing a decrease in retinal sensitivity and fixation quality when the disease progresses [20]. There are also studies presenting microperimetry (MP-1) diagnostic utility in the evaluation of the disorders of the optic nerve such as epidemic optic neuropathy (EON) [21][22][23][24][25][26], dominant optic atrophies (DOA) [27,28], LHON [26][27][28][29][30], thyroid associated orbitopathy to the (TAO) [27,28,31] and multiple sclerosis [27,28,32].…”

BaCKground: Leber's hereditary optic neuropathy (LHON) is a disease associated with pathogenetic mutations of mitochondrial DNA which affects predominantly young adult males and leads to loss of central vision, low visual acuity and unstable fixation. The purpose of this study was to allow the patient to establish the best possible fixation in the best area of retinal sensitivity in LHON patient with central scotoma. Methods: A 17 years old patient with confirmed mitochondrial LHON 11778G > A mutation was included in the study. The patient underwent 16 visual rehabilitation sessions-two for each of 8 weeks using the training module available in the equipment-MAIA microperimeter. Visual acuity and standrad microperimetry examination were performed before and 8 weeks period of training. To measure the fixation stability with MAIA microperimeter, P1, P2 and Bivariate Contour Ellipse Area (BCEA) parameters were used. results: Visual acuity of the trained better eye was 0.08 at the baseline versus 0.063 after 8 weeks training. Fixation stability parameter was P1-21%, P2-64% at the first session versus P1-60%, P2-90% at the last session. BCEA values 29.2°² before and 14.2°² after training, respectively. ConClusions: Visual training via microperimetry could potentially be a method that improves the fixation stability in patients with LHON.

“…Based on this, we can understand the utility of microperimetry in other areas besides visual rehabilitation and why a variety of research studies focus on new treatments for macular diseases and the effectiveness of microperimetry [12–14]. Additionally, it has been proved that microperimetry is a useful tool for the follow-up of patients with diabetic retinopathy [15–18], central serous chorioretinopathy [19, 20], uveitic macular edema [21], macular dystrophies such as Stargardt disease [22], and AMD, in the latter evidencing a decrease in retinal sensitivity and fixation quality when the disease progresses [23]. …”

BackgroundAge-related macular degeneration (AMD) is the leading cause of blindness in the western world. As a consequence of AMD, patients develop structural damage that comprises the fovea and subsequently present loss of central vision, low visual acuity and unstable fixation. Contrary to what happens with anti-angiogenic treatment in neovascular AMD, there is currently no definitive treatment to reverse geographic atrophy progression. The aim of this study was to determine the effectiveness of the visual rehabilitation treatment via microperimetry in patients with geographic atrophy.MethodsLongitudinal and prospective study, 18 patients with areas of geographic atrophy in their eye of better visual acuity were included. Macular integrity assessment (Maia) microperimeter (CentreVue, Padova, Italy) was used to diagnose retinal fixation and sensitivity in these patients. Based on these data and using the training module available in the equipment, the patients underwent visual rehabilitation sessions intended to allow the patient to establish the best possible fixation in the best area of retinal sensitivity. To determine the training effectiveness, the following variables were compared before and after: visual acuity in LogMAR scale with ETDRS charts, reading speed with Minnesota Low-Vision Reading Test (MN Read), average sensitivity threshold in microperimetry; P1 and 95% Bivariate Contour Ellipse Area (BCEA) values were used for fixation stability measurement.ResultsMean age was 77 years old (65–92). Visual acuity of the trained eye was on average 0.7 versus 0.6 LogMAR (p = 0.006) before and one week after training. Reading speed, using both eyes, was 47 words per minute (wpm) before training and 69 wpm after training (p = 0.04). Average retinal sensitivity was 14.1 versus 14.6 db (p = 0.4). Fixation stability improved with P1 values of 45% versus 51% (p = 0.05) and 95% BCEA values of 43 versus 25 (p = 0.02) before and after training, respectively.ConclusionsVisual training via microperimetry in patients with age-related macular degeneration is effective in improving fixation stability, reading speed, and visual acuity, measured one week after training is completed.

Does Microperimetry Have a Prognostic Value in Central Serous Chorioretinopathy?

Abstract: Microperimetry with a cutoff of 20 dB may be a useful test to predict the persistence of subretinal fluid, allowing the ophthalmologist to use treatment tools earlier, preventing extracellular damage and visual impairment.
