Clinical Management Guidelines (CMG) Lecture Notes

Overview

  • Focused on preparation for clinical exams related to eye care and diseases.
  • Breakdown of guidelines into anatomical categories: eyelid, conjunctival, corneal, glaucoma, posterior segment conditions, trauma.
  • Emphasis on organized study and breaking down information into manageable parts.

Eyelid and Eyelash Conditions

  • Eyelid Conditions: Blepharitis, hordeolum (stye), psoriasis, trichiasis.
  • Tear Ducts: Issues related such as dacryocystitis.
  • Skin Conditions: Including basal cell carcinoma (BCC) which is detailed in clinical assessments.
  • Exam Tips: Sleuth for subtle signs like unilateral presentation or absence of eyelashes.

Conjunctival Conditions

  • Divided into inflammatory and non-inflammatory categories.

Inflammatory:

  • Conjunctivitis, scleritis, episcleritis.

Non-inflammatory:

  • Pigmented lesions, concretions, scarring, subconjunctival hemorrhages.

Corneal Conditions

Categories:

  • Infectious: Herpetic keratitis, microbial keratitis.
  • Inflammatory: Graft rejections, marginal keratitis, photokeratitis (snow blindness).
  • Non-infectious/Non-inflammatory: Abrasions, foreign bodies, dystrophies, corneal erosions.

Glaucoma and Anterior Chamber Conditions

Glaucoma Categories:

  • Open Angle Glaucoma: Diagnosis includes ongoing pressure management.
  • Angle Closure: Immediate attention and possible surgical intervention.
  • Steroid-induced: Management through reduced steroid use and pressure control.
  • General Guidelines: Emphasize comprehensive assessments beyond just pressure measurements. Look for visual fields, retinal nerve fiber layer, optic disks.
  • Therapies: Begin with prostaglandin analogs, consider beta blockers next, potential for more invasive treatments.
  • Referral Protocols: Follow up based on risk level.
  • Patient Education: Emphasize glaucoma is usually manageable with proper treatment.

Posterior Segment Conditions

  • Conditions: Retinal vein occlusion, macular hole, endophthalmitis.
  • Clinical Impact: Ensure proper differential diagnosis and informed decision-making on treatments.

Trauma Conditions

Categories:

  • Blunt Trauma: Common sports-related injuries.
  • Chemical Trauma: Acid/alkali exposure.
  • Penetrating Trauma: Rare but serious, generally requiring hospital intervention.

NICE Guidelines on Glaucoma (NG81)

  • Overview: Emphasizes guidelines on diagnosis and long-term management for adults only.
  • Diagnostic Approach: Avoid reliance on intraocular pressure alone, consider comprehensive eye health metrics.
  • Patient Management: Tailored follow-up intervals based on individual risk assessments.
  • Therapeutic Hierarchy: Start with prostaglandin analogs, proceed to beta blockers if necessary.
  • Clinical Responsibility: Encourage ongoing self-education and proactive patient counseling.

Specific Case Studies and Polls (Lecture Interactive Segment)

  • BCC Case: Analysis and differentiation from other conditions, primarily based on clinical presentation, patient history, and typical lesion characteristics.
  • Glaucoma Management: Emphasis on choosing appropriate medications and follow-up schedules based on patient presentation and treatment response.

Bell's Palsy and Facial Nerve Palsy

  • Overview: Bell's palsy linked to unknown causes typically affecting the 7th cranial nerve (facial nerve).
  • Assessment: Check functional impact on eye closure, facial expressions, and tear/saliva production.
  • Management: Eye protection is critical, alongside potential medical therapy for underlying causes.
  • Differential Diagnosis and Education: Awareness of other conditions mimicking similar presentations.

Pupil Abnormalities

  • Types: Physiological anisocoria, Horner's syndrome, Adie's pupil, Argyle Robertson pupil.
  • Clinical Signs and Diagnostics: Pupil reaction differences under light/dark conditions, associated systemic conditions.
  • Emergency Signs: Recognizing when imaging or urgent referral is necessary.

Pigmented Choroidal Lesions

  • Types: Choroidal nevi, melanomas, melanocytomas.
  • Clinical Significance: Monitoring for changes, potential for malignancy, role of genetic factors in prognosis.
  • Diagnosis and Treatment Options: Importance of recognizing suspicious features early, range of treatment modalities.

Final Exam Preparation and Pearls of Wisdom

  • Study Techniques: Focus on guidelines and common-sense clinical decision-making, with emphasis on clear differentiation between conditions.
  • Exam Strategy: Understand the structure of questions, avoid overthinking, manage time effectively.
  • Ongoing Education: Importance of continuous professional development post-qualification.
  • Community Advice: Valuable tips from experienced optometrists.

Key Takeaways

  • Break down study topics into categorized chunks for better grasp and retention.
  • Understand the flowcharts and guidelines for practical application in both exams and clinical practice.
  • Stay calm, logical, and methodical in both preparation and examination settings.
