The widespread use of digital devices like smartphones, computers, and televisions has become an essential part of daily life across all age groups. Communication, education, work, and recreation demand their compulsory use. Prolonged screen exposure is linked to a cluster of visual symptoms known as Digital Eye Strain (DES). Let us understand the issues one by one. Light emitted from smartphones Causes constriction of pupil → miosis → leading to convergence → difficulty in reading.  Blue spectrum of smartphones decreases melatonin production, a hormone controlling sleep-wake cycles → sleep disturbances → insomnia + mental fatigue → dry eyes + tactile hallucinations.  Refractive change → myopia due to exposure to light from smartphones and reduced outdoor activity time.  IOP – Smartphone use demands ocular adjustments for near vision → increased demand for accommodation and vergence → increased IOP.  IOP rise is faster in eyes with anterior chamber depth less than 2....

Imagine staring at a computer screen during a high-stakes deadline, your heart racing as stress builds - unbeknownst to you, this invisible tension is quietly raising pressure in your eyes, potentially fuelling glaucoma’s silent advance. Science now reveals how mind and body are locked in a delicate dance, where psychological states profoundly influence biological processes, and vice versa. The Mind-Body Link in Glaucoma Psychological stress can trigger two key hormonal pathways: HPA Axis : Stress prompts the hypothalamus to release CRH (corticotropin-releasing hormone). CRH stimulates the pituitary gland to release ACTH (adrenocorticotropic hormone), which in turn prompts the adrenal glands to release cortisol. Elevated cortisol levels can increase intraocular pressure (IOP). SAM Axis : Stress activates the sympathetic nervous system, stimulating the adrenal medulla to release adrenaline and noradrenaline. This elevates IOP and causes vasoconstriction in retinal and optic nerve vessel...

Aging brings loss of vision due to loss of transparency in the crystalline lens of the eye and the condition is known as Cataract . No medicine can cure it, so surgery to remove the opaque lens and replace it with an artificial lens is the only remedy. With the advent of microscopes and phaco machines, cataract surgery has become a miracle bringing great visual results. But surgery has its own challenges. Here, we as surgeons are afraid of infection leading to endophthalmitis and the second is intraoperative drownings of the crystalline lens in the vitreous chamber. Either of the two complications can lead to visual damage and phthisis - softening of the eyeball to the shrunken small eye. So though results are the best most of the time, it cannot be so each and every time and complications can occur. What are the expectations of a cataract patient going for surgery? Though this may sound to be a simple question, the answer is a bit complicated. I will start from the expectations. one b...

We planned a week’s visit to an old-age home in Lonavala, in a group of ten from Bilimora between 7 and 14-Mar-2019. Dr. Pravin Gilitwala led the team and organised because he had been there numerous times. Dr. Bhavana Desai (my wife) and I were little uncertain about the venue and timetable there but agreed just to have a new experience altogether. To our surprise, everything turned out to be better than all we thought. We had a great time all in all! Kapol Sanatorium, Lonavala Just by the old Mumbai-Pune highway is situated this old-age home for fixed one week stay. Only old-age people above 60 years are invited to stay for a week starting every Thursday and ending the next Thursday, in a total number of hundred. There are AC and non-AC rooms available for fixed one week, at different rates. These are twin-sharing rooms charged at is Rs. 6,000 and Rs. 12,000 per week, based on individual preferences. The rooms are like single bedroom apartments with four beds, dining table ...

Blindness is a state of being sightless or say an inability to see . World Health Organization - WHO (1972) describes blindness as the inability to count fingers at the distance of 3 meters in day-light after best possible spectacle correction in the better eye OR visual field less than 10° around the centre of fixation. Blindness is of three TYPES: Loss of visual acuity. Colour blindness: Inability to recognize colours, and Night blindness: Night vision is damaged.

I was one of the brightest of students during my academic career. I respected my teachers and I was their favourite student. I have studied up to 28 years of age to pass M.S. in Ophthalmology and practised for 32 years. I know practising in a small village-like town does bring more practice and less money. I was the only eye specialist available serving needy poor of the area for more than two decades . I have worked as honorary visiting eye-surgeon at Eye camps organized at Adivasi (tribal) and poor areas of Vansda, Ahwa, Dharampur for a long time - at Gram Seva Trust, Kharel and Bodhi Gaya (Bihar) eye-camps for more than five years. I am working at Rotary Eye Hospital, Chikhali till today in addition to my private practice .
