A Stamford ophthalmologist was fined $4,500 Tuesday by the state Medical Examining Board for performing a laser treatment on the wrong eye of a glaucoma patient. Dr. Gregory Gallousis performed the procedure in 2012 on the right eye of a glaucoma patient instead of the left eye, state Department of Public Health records show. The patient was supposed to have surgery on both eyes, but not on the same day, Matthew Antonetti, a principal attorney for DPH, told the board. Gallousis agreed to the fine by signing a consent order with the state. On Tuesday, the board rejected a consent order that would have fined Dr. Alkesh Patel of Southington $5,000 and reprimanded him for prescribing large amounts of the painkiller Dilaudid in 2012 for his wife, an employee and a patient, state records show.
