Computer Vision Clinic

The computer vision clinic caters to the visual needs of individuals who suffer from visual problems due to gadget and computer use. In the present technology world, efficient visual functioning takes a back seat with prolonged use of computers and gadgets. Computer users face a wide variety of health issues ranging from dryness of eyes, musculoskeletal dysfunctions and binocular vision issues. Hence the clinic focuses at understanding the visual system and ergonomic factors through administration of a detailed questionnaire followed by assessment of binocular vision and ocular surface dryness. Appropriate recommendations are provided based on the examination findings.

Vision Therapy Clinic

The goal of vision therapy is to optimize the visual system, and areas of the brain that control vision, visual efficiency, visual perception and other vision-related functions. By treating the entire visual system, vision therapy aims to change reflexive (automatic) behaviours to produce a lasting cure. Vision therapy can treat vision problems that interfere with efficient reading among schoolchildren. It provides treatment for amblyopia (lazy eye), learning related vision problems, traumatic/acquired brain injuries. It also can help reduce eyestrain and other symptoms of computer vision syndrome experienced by many children and adults that cannot be treated successfully with eyeglasses, contact lenses and/or surgery alone, and help people achieve clear, comfortable binocular vision.

BAND study

Binocular vision is an important aspect of vision testing and efficient binocular vision is necessary for efficient reading skills in children and adults. Binocular vision anomalies can significantly impair the reading and learning performance of children. Generally a Vision screening program will focus at screening for refractive errors and other significant visual/ocular morbidities. Unless tested for the Binocular vision parameters, Binocular vision anomalies can be missed out in the routine screening or even in clinical practice. The community aspect of the binocular vision clinic, through the BAND (Binocular vision anomalies and normative data) study has addressed this issue in estimating the visual morbidity of binocular vision anomalies among school children. The study has also successfully tested the efficacy of vision therapy in a community set-up.

Another aspect of community responsibility of the binocular vision clinic is to support the occupational optometry services of Elite school of Optometry, helping to understand the visual demands pertinent to binocular vision in various occupations.

Binocular Vision lab

The Binocular vision research lab at the Srimathi Sundari Subramanian Department of Visual Psychophysics (SSDVP) focuses on understanding mechanisms of accommodation and vergence in subjects with binocular vision anomalies.

Convergence Insufficiency

Convergence insufficiency (CI) remains the most common binocular vision disorder affecting children and adults, the prevalence of which accounts to 30% based on our data from BAND study. Binocular vision clinic having understood the need for quality research in CI carries out many projects in this field. The current research work on Convergence insufficiency (CI) aims to demystify the underlying mechanism and the interaction between vergence and accommodation in CI. The lab focuses on understanding the changes in the cross-link ratios of AC/A and CA/C in CI pre and post vision therapy using WAM-5500 Open field Autorefractometer (Grand Seiko, Japan). The CI participants undergo a comprehensive binocular vision examination following which standardized in-office vision therapy treatment is advised. The resultant change in binocular vision parameters and changes in the cross-link ratios are assessed post vision therapy.

The study has been completed and the research details can be accessed at http://www.sciencedirect.com/science/article/pii/S1888429616300693
Adult Amblyopia
Adult Amblyopia

Clinical research in Adult Amblyopia (14 years to 35 years of age) is less known and practiced in India. A current research work involves the advice of Action Videogames for those patients with impaired visual acuity, causes being anisometropic, Strabismic and mixed amblyopes, the improvement/changes of visual functions are noted. One of our objectives is also to observe whether this innovative treatment modality can yield a long term sustainability of visual functions.

Myopia Research

Myopia Research

With worldwide increasing prevalence of myopia (short-sightedness), increased attention is paid to this area to combat the growing prevalence and to better the quality of life of these children. The Myopia research at the Srimathi Sundari Subramanian department of visual psychophysics has reported the characteristics of near induced transient myopia in Indian population. Another interesting variant of myopic presentation in the Indian ethnicity, which has not been reported in literature so far, is also one of the key researches at the department. Further research focuses on understanding optical and ocular biometry parameters of Indian variant myopia.

Neuro-Optometry

Neuro-Optometry clinic, the first of its kind in India serves individuals with visual issues due to Acquired brain injuries, Traumatic brain injuries and brain stroke. Brain injuries are one of the major public health concerns. Statistics show that 40 % of the traumatic brain injury cases are due to Road-traffic accidents. These neurologically challenged individuals are afflicted with a variety of binocular vision and eye movement disorders. In the Neuro-Optometry clinic, Developmental eye movement test (DEM) and ReadAlyzer are used to assess the important aspects of eye movements. The current work at the clinic aims at understanding visual efficiency and eye movement disorders and also focuses on developing the normative data for DEM and ReadAlyzer in Indian Population.

Fellowship

The Binocular vision and Vision therapy fellowship program is a 6 months program designed to provide intensive clinical experience in binocular vision care, and vision therapy . The fellow will have the opportunity to work with the diverse population at the Binocular vision / Vision therapy clinic and the pediatric clinic. The fellow will also be trained in clinical teaching and research and have the opportunity to teach undergraduate students.

Residency program

The Residency program is a one year Intensive clinical training program in Pediatric Optometry, Binocular vision and Neuro-Optometry. This clinical work will consist primarily of clinical posting in the Binocular Vision / Vision Therapy clinic / Neuro-Optometry clinic and in the Pediatric Ophthalmology outpatient department with Pediatric Ophthalmologists, Optometrists and in independent patient care. At least 85 percent of the clinical time would be spent in these clinical postings, allocation of balance time would be determined in consultation with an advisor. Teaching, clinical research and other requirements will fill the remaining part of the schedule.
