Tetralogy of Fallot (TOF), formerly known as Steno-Fallot tetralogy, [9] is a congenital heart defect characterized by four specific cardiac defects. [4] Classically, the four defects are: [ 4 ] pulmonary stenosis , which is narrowing of the exit from the right ventricle;

The Trilogy of Fallot also called Fallot's trilogy is a rare congenital heart disease consisting of the following defects: pulmonary valve stenosis, right ventricular hypertrophy and atrial septal defect. [1] It occurs in 1.2% of all congenital heart defects. [2]
Microphthalmia is a congenital disorder in which the globe of the eye is unusually small and structurally disorganized. [2] [4] While the axis of an adult human eye has an average length of about 23.8 mm (0.94 in), a diagnosis of microphthalmia generally corresponds to an axial length below 21 mm (0.83 in) in adults.
Pediatric ophthalmologists are qualified to perform complex eye surgery as well as to manage children's eye problems using glasses and medications. Many ophthalmologists and other physicians refer pediatric patients to a pediatric ophthalmologist for examination and management of ocular problems due to children's unique needs.
It is characterized by small eyes, a diaphragmatic hernia, and Tetralogy of Fallot, a congenital heart defect. [2] [3] The only known case is of a 9-year-old boy with several congenital anomalies including a diaphragmatic hernia, microphthalmia, and Tetralogy of Fallot. It was found that the boy had a reciprocal translocation t(1;15)(q41;q21.2 ...
The Marcus Gunn pupil is a relative afferent pupillary defect indicating a decreased pupillary response to light in the affected eye. [3] In the swinging flashlight test, a light is alternately shone into the left and right eyes. A normal response would be equal constriction of both pupils, regardless of which eye the light is directed at.
The circumferential extent of the disease is described in segments as if the top of the eye were 12 on the face of an analog clock, e.g. stage 1 from 4:00 to 7:00. (The extent is a bit less important since the treatment indications from the Early Treatment for ROP.) [13]
