The anterior segment of the eye, comprising the conjunctiva, cornea, eyelids, and surrounding structures, is the site of the most frequently encountered ocular complaints in primary care, pediatric, and emergency settings worldwide. Conditions ranging from the common bacterial conjunctivitis to the more serious corneal ulcer present with overlapping symptoms such as redness, discharge, and discomfort, making accurate differential diagnosis a genuine clinical challenge for non-specialist practitioners. Misdiagnosis is common: studies show that up to 60% of conjunctivitis cases receive unnecessary antibiotic prescriptions, while sight-threatening conditions like corneal ulcers are sometimes undertreated due to delayed referral. ProdigEye was designed to close this gap, providing frontline clinicians with AI-powered diagnostic support at the point of care, using only a standard smartphone camera. The conditions listed below represent the full spectrum of anterior segment pathologies that ProdigEye is trained to identify and support, enabling faster, more accurate clinical decisions that improve patient outcomes and reduce unnecessary healthcare burden.
Bacterial Conjunctivitis
- Markedly red eye with mucopurulent (yellow or green) discharge
- Usually caused by Staphylococcus aureus, Streptococcus pneumoniae, or Haemophilus influenzae
- Frequently starts unilateral, can become bilateral
- Responds well to topical antibiotic drops
Viral Conjunctivitis
- Viral origin, usually Adenovirus
- Eyes are red, watery, and may have discharge
- Patients often suffer from URI (Upper Respiratory Infection) or sore throat (Pharyngitis)
- Highly contagious, spreads easily by hand-to-eye contact
- Treated with combination topical steroid-antibiotic drops or ointment
Allergic Conjunctivitis
- Allergic response to allergens like pollen, dust, or pets
- Redness, itching, and tearing
- Usually bilateral but may be asymmetric
- Treated with antihistamine drops and tablets
Blepharitis
- Inflammation of the eyelids
- Redness, swelling, and crusty eyelashes
- Often due to Demodex mites overgrowth on lashes
- Significant risk factor for Chalazion (stye) and Dry Eye
Subconjunctival Hemorrhage
- Bright red patch of blood beneath the conjunctiva (surface of the eye)
- Caused by leakage from a torn blood vessel after lifting heavy objects or coughing (Valsalva)
- Risk factors include hypertension and use of anticoagulants (blood-thinners)
- Painless and does not cause vision loss
Corneal Foreign Body
- Metal, sand, or dust particles embedded on the cornea
- Causes stabbing pain, redness, and tearing
- Rust rings may form around metallic foreign bodies
- Requires prompt removal and antibiotic drops to prevent infection and corneal scarring
Corneal Ulcer (Keratitis)
- Open infection on the corneal surface, usually caused by bacteria
- Pain, redness, photophobia, and a visible white opacity (infiltrate) on the cornea
- Untreated cases can potentially lead to perforation and permanent visual loss
- Requires urgent referral to an ophthalmologist or Emergency Room for broad-spectrum topical antibiotics
- Risk factors include contact lens overuse or sleeping in lenses
Chalazion (Stye)
- Tender or painless lump on the eyelid caused by blockage of meibomian (oil) glands
- Can lead to eyelid swelling and even facial skin infection (cellulitis)
- Treated with combination steroid/antibiotic ointments and warm compresses
Pterygium
- White or red triangular growth extending onto the cornea, usually nasally (near the nose)
- Symptoms include irritation, dryness, and blurred vision
- Caused by chronic exposure to sun (UV light) and wind
- Treated with artificial tear drops; surgical excision performed if causes significant astigmatism
